Going wrong somewhere with the .prev() method in jQuery.

This is the code I am using for the 2nd objective - $('li').eq(2).prev();

What am I doing wrong?

Help is welcomed.

  <h2>Student List</h2>

  <ul class="student-list">
    <li>James McAvoy</li>
    <li>Alena Holligan</li>
    <li>Wade Christensen</li>
    <li>Matt Krzyzynski</li>
  </ul>

  <script src="jquery-3.2.1.min.js"></script>
  <script src="app.js"></script>

</html>
app.js 
$("li").eq(2).prev();

The instructions ask you to "traverse from Wade Christensen to James McAvoy in the list of students."

But James McAvoy is not the student immediately previous to Wade Christensen, so using "prev()" just one time will return a different student.

And happy coding!
